Acute plant poisoning: Analysis of clinical features and circumstances of exposure

Fuchs, J. Acute plant poisoning: Analysis of clinical features and circumstances of exposure. 2011, University of Zurich, Faculty of Medicine.

Abstract

Human contact with potentially toxic plants, which may occur through abuse or by accident or attempted suicide, is frequent and sometimes results in clinically signifi cant toxicity. Objective. The aim of the present study was to identify which plants may lead to severe poisoning, and to defi ne the clinical relevance of plant toxicity for humans in Switzerland. Methods . We analyzed 42 193 cases of human plant exposure and 255 acute moderate, severe, and lethal poisonings, which were reported to the Swiss Toxicological Information Centre between January 1995 and December 2009. Results . Plant contact was rarely responsible for serious poisonings. Lethal intoxications were extremely rare and were caused by plants with cardiotoxic ( Taxus baccata ) or mitosis-inhibiting ( Colchicum autumnale ) properties.Conclusions . Most often, plant contact was accidental and patients remained asymptomatic or developed mild symptoms, which fully resolved within a short time.

Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
